## Abstract The ^13^C NMR chemical shifts for 1,3‐dithiolane and 13 methyl substituted derivatives are reported. Substituent effects are derived and compared with those for cyclopentanes and 1,3‐dioxolanes. The magnitude and variety of the substituent effects are best explained with the aid of a ha
